The incidence of SAEs will be calculated by preferred term (PT) by overall and with/without causal relationships with VAXZEVRIA assessed by investigator(s).From the next day of 28 days after the last vaccination of VAXZEVRIA up to 12 months after the last vaccination.The incidence of SAEs (including thrombosis in combination with thrombocytopenia, immune-mediated neurological conditions and VAED including VAERD, thrombosis or other diseases) will be calculated by preferred term (PT) by overall and with/without causal relationships with VAXZEVRIA assessed by investigator(s).
Number of the subjects considered to be severe case of COVID-19 and its incidence (%) will be calculated. The subject who required a hospitalization in intensive care unit or use of respirator will be defined as a severe case.From the next day of 28 days after the last vaccination of VAXZEVRIA up to 12 months after the last vaccination.Number of the subjects considered to be severe case of COVID-19 and its incidence (%) will be calculated. The subject who required a hospitalization in intensive care unit or use of respirator will be defined as a severe case based on the severity classification reference of A guide for front-line healthcare workers (MHLW, 2020).
